The guide for by A.P. Ershova and V.V. Goloborodko (Ершова А.П., Голобородько В.В.) focuses on using its unique tiered structure to master the curriculum and prepare for exams like the OGE. 🛠️ Workbook Overview

This manual is a standard in Russian-language mathematics education for its "differentiated" approach.

Sine and cosine theorems for solving triangles. Vectors: Operations with vectors and coordinate geometry. Polygons: Areas and properties of regular polygons. Transformations: Rotations, symmetry, and translations. 💡 How to Use the Guide Effectively

Advanced/Olympiad-lite problems for high marks and deep understanding.

Includes independent (самостоятельные) and control (контрольные) works for both algebra and geometry in one book. Three Levels of Difficulty: Level A: Essential basics for passing grades.

Start with Level A of any topic. If you solve it in under 15 minutes with no errors, skip straight to Level C to challenge yourself for the OGE.

You can find the latest editions (often revised for current FГОС standards) at retailers like: Knizhka US ($21.00 - $24.00).

Based on standard Russian federal curricula often tested in Ershova's works:
